They found a solitary nodule on the Lung of my 8 year old son found on chest xray and CT scan. Orignally took my son to the doctor because he was complaining of chest pain and headaches daily. They sent him for a chest xray and it came back showing a solid nodule about 14mm big. He then went for a CT scan w/o contrast. Here is the results of the CT scan.....

Findings: There is a 18mm lobulated right upper lobe nodule abutting the pleural surface. It contains indeterminate type internal calcifications. Lungs are otherwise clear. Thymic tissue in the anterior mediastinum. There is axillary adenopathy, The results recommend PET/CT to assess for metabolic activity. Additonally, biopsy may be considered.

Per the Pulmonary specialist he saw they do not want to look into thiks any further. The tested him 3 times for Valley Fever and they all came back negative. They also tested him for TB which was negative. They said if they saw this type of CT on a 45 year old they would be concerned but since he is 8 they think it is nothing. It makes me very uneasy as they cant tell me what cause it. It just bugs me that they so easily dismiss this because of his 8 and cant give me any type of answer. She I demand they do a PET scan or biopsy it? Should I be concered? If its not cancerous what else could it be?
